I own a 01 RMK 700,slp single pipe, vf3 reeds,spacers,bottle boost. Running 10-62 weights,slp black red spring, 52 34 slp helix,stock silver blue secondary spring.Raced it all year did ok. But when I skipped water it would only pull 6500 rpm.Put stock helix in & pulled 8100 rpm,stock is a r11,forget angle.When I rode it all year it would only turn 7600 and pull slow to 7800.Also slight bog 100ft off the line.Ithink I Have too aggressive helix,someone said too heavy weights.Also this is at sea level. Thanks

sounds like too heavy of weight and possible too aggressive of an angle helix for your setup. your motor is putting out enough. drop to the 10-60's, i dont know what to tell u about the helix though
